2 Claims. (01. 200-468) This invention relates to vibrators.

An object of the invention is to improve the construction and the support for the vibratory element.

Other objects of the invention will be apparent from the description and the claims.

In the drawings, the flgure shows a longitudinal cross section of a vibrator embodying features of the present invention.

The pres nt invention contemplates an improved vibrator support and sound isolating member. In its preferred form the member comprises a tubular body of sponge rubber having flaring conical flanges at its ends for supporting the vibratory element within its container.

Referrin to the drawings, the vibrator comprises a cylindrical can I having an internal bead 2 near its free end. A disc 3 of insulating material is fltted within the end of the can and the free edge of the can is spun over the disc to hold it against the bead 2. Connecting prongs 4 are mounted in the disc 3 for plugging the vibrator into an electric socket.

The vibrator element 5 within the can is connected by flexible insulated wires Ii to the prongs. Element 5 may be a vibrator of the type shown and described in Slater Patent No. 2,190,685 for example, or of other types known in the art.

' The present invention is concerned particularly with the supporting member 1 for supporting vibrator element 5 within the can. While element I can be made of a variety of resilient or compliant materials, it is preferably molded as a single piece of sponge rubber. The element comprises a cylindrical body portion 8 having end walls or flanges 9 provided with central apertures In. Each end of the body is provided with flaring conical flanges ll extending from the edges of end walls 9 diagonally outward. The outer diameter of the flanges is substantially equal to the inner diameter of can I. Flange II at the upper end of the can, therefore, extends substantially to the junction of the cylindrical wall with the end wall of the can. The lower flange ll may rest against end disc 3 or may rest ainst the internal bead 2 as shown.

By using a support of this construction the vibratory element 5 has a high degree of compliance with respect to the container. However, the support is sufllciently stifi to hold the vibrator centered in any orientation, thus maintaining air spaces on all sides of the vibrator. Moreover, when the unit is subjected to extreme accelerating forces, such as those produced .by dropping, the vibratory element is positively prevented from coming into direct contact with the can. A layer of the resilient material is always interposed. The support also returns, the vibratory element to a central position as soon as the accelerating forces have ceased.

The apertures III in both ends or the body permit assembly from either end. An added advantage of this construction is that it utilizes a very small amount of material.

While sp'eciflc embodiments of the invention have been described, it is intended to cover the invention broadly within the spirit and scope of the appended claims.

What is claimed is:

. 1. A vibrator lining member comprising a symmetrical body integrally molded of sponge rubher having a hollow cylindrical mid-portion, an outwardly flaring conical flange integrally formed with and extending from each end of said cylindrical portion, and an inwardly extending flange integrally iornred with and protruding into each end of said cylindrical portion defining a pair of apertures, said inwardly extending flanges being elastically deformable by stretching to permit introduction of a vibrator endwise into said member through enlargement of either one of said apertures and being adapted to restrain the inserted vibrator against displacement relative to said mid-portion, and said outwardly flaring flanges being adapted to engage terminal regions of the interior of a mounting can to resiliently support the lining member.

2. A liner member of compliant rubber-like material for vibrators of the class wherein an elongated eletromagnetic vibratory interrupter is mounted in a cylindrical container, said liner member comprising a hollow tubular mid-portion adapted to sheath an interrupter, an integrally formed outwardly flaring conical flange at each end of said mid-portion extending substantially to the junction of the cylindrical wall of the container with the end walls thereof to resiliently support said tubular mid-portion out of contact with said container, and an integrally formed inwardly extending flange at each end of said midportion" restraining the sheathed interrupter against axial displacement and defining a pair of apertures, said outwardly and inwardly extending flanges forming an integral and symmetrical structural unit with said mid-portion of the lining member, and said inwardly extending flanges being sufliciently deformable to permit insertion of an interrupter endwise into said member through either one or said apertures.
